Are you kidding? Did he really do an impersonation of a person with Parkinson's disease?
I think that WT is probably still sleeping, but I watched it late last night. It was probably totally unconscious on Kerry's part, but when he was talking about Michael J. Fox, he couldn't think of the word, "Parkinson's," and he shook his hand in the air like a person with Parkinson's trembles.
I'm sure he didn't even know he was doing it, but it looked kind of awful.
